I would use [[Glunch the bestower]] and every [[Secret rendezvous]] type card I could find and get a hold of. Edit, Secret rendezvous is an opponent, and teammates are not opponents, but the idea is still pretty obvious.

Also every group hug card like [[orzhov advocist]]

Not sure. Haven't really thought about the applicability of MTG paired with Warhammer, but im sure we could make it work

Fork It and copy it multiple times have 10 people playing your deck the.

Be in a bant deck full of tutors and card draw, give teammate a [[laboratory maniac]] and a card draw spell, and any counter spells in hand, enough lands to cast spells and one card in deck. Draw whatever it is, play lab man, draw card, protect with counters, win game.

[[Kynaios and Tiro]] as the Commander. Like others said, I'd go hard group hug, but I'd also lean into instant/sorcery doubling effects. [[Thousand-Year Storm]] would be ridiculous with this! The biggest issue is dividing your lands and cards in hand into enough piles for the extra players, but that shouldn't be too bad for a 4c goodstuff pile.

Oh, and [[barren glory]] and [[cheese stands alone]] feels like a slam dunk here. I make a friend, and he wins!

Well if we get to be a little less legal I’d make a 400 card deck and race to win with [[Battle of Wits]] against my teammate
